About the 2081-9063

Dual channel, transformer-isolated intrinsically safe barrier module for Simplex initiating device circuits. It limits the circuit current below the ignition level so the wiring can run into hazardous locations of NEC Classes I, II and III, Divisions 1 and 2, Groups A to G. Each module needs a 2081-9061 installation kit and a 2975-9218 cabinet.

Intrinsically safe circuits are for indoor use only, cannot be used with alarm verification, and must not share cable, conduit or raceway with other circuits.
